Device for pressurized transfer of e.g. lubricating oil in four stroke heat engine of motor vehicle, has fluid inlet and fluid outlet respectively arranged in two zones of camshaft whose rotation forms Archimedean screw to transfer fluid

摘要

The device has an inner conduit (5) extending from one zone to another zone of a camshaft along length of the camshaft, where the camshaft is provided with an axle (10). The inner conduit is formed in a helical shape such that an Archimedean screw is formed by rotation of the camshaft for transferring fluid inside the camshaft. A fluid inlet i.e. inlet bearing (20), supplies the fluid into the inner conduit. A fluid outlet i.e. outlet bearing, discharges the fluid from the inner conduit, where the inlet and the outlet are respectively arranged in the two zones.
